Answer : 3. "ribosome"
Explanation :
Protein synthesis takes place in the cell on ribosomes. Ribosomes are cellular structures composed of RNA and proteins, and they are the sites where amino acids are linked together to form proteins, following the instructions encoded in messenger RNA (mRNA) molecules. This process, called translation, is a fundamental cellular mechanism essential for the synthesis of various proteins necessary for the functioning of the cell and the organism as a whole. Ribosomes can be found both in the cytoplasm of the cell and attached to the endoplasmic reticulum in eukaryotic cells.

Explanation :
Kharif crops – The crops sown in June-July in the Indian subcontinent are called Kharif crops. These crops are harvested in October and November. These require high temperature and humidity at the time of sowing and dry environment at the time of ripening.
Main Kharif crops – Cotton, groundnut, paddy, millet, maize, sweet potato, urad, moong, moth cowpea (Chanwala), jowar, arhar, dhaincha, sugarcane, soybean, okra, sesame, guar, jute, flax etc.

Answer : 1. "Richter "
Explanation :
The Richter magnitude scale (often shortened to Richter scale) was developed to assign a single number to quantify the energy that is released during an earthquake. An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth’s crust that creates seismic waves.

- SingleChoice
Answer : 4. "barometer reading rises suddenly"
Explanation :
A falling barometric pressure, detected by a barometer, signals an approaching thunderstorm. This drop indicates unstable atmospheric conditions, often preceding stormy weather. Meteorologists use barometric readings to predict thunderstorms, as the decrease in pressure signifies the likelihood of imminent weather disturbances and allows for timely weather warnings.
